Abstract
A stator assembly for a linear motor includes a plurality of interleaved modular pieces. Prewound coils and spacer pieces are alternately provided along the length of the stator. The spacer pieces have a generally trapezoidal cross section, complementary to a trapezoidal cross section of the prewound coils. Rims may be provided at an inner region of the spacer pieces. At the outer edge of the spacer pieces is provided a wall which mates with the identical wall on an adjacent spacer piece. The spacer piece may have radial slots cut entirely and/or partially through the piece in order to reduce the current and eddy currents induced when the prewound coils are energized.
